+From 3cd31a44e61e2219d730d6b1a4a13c8e15d6e395 Mon Sep 17 00:00:00 2001
+From: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>
+Date: Thu, 2 Apr 2020 19:54:33 +0200
+Subject: [PATCH] ARM: dts: overlays: Unify overlay CMA handling
+
+Now that we don't have to abuse the kernel command line to change CMA's
+size we can clean-up and centralize CMA usage in overlays.
+
+A new file, cma-overlay.dts is created to be used as a standalone
+overlay or included on other overlays. All CMA users are converted to
+this scheme. Ultimately upstream-overlay.dts is also updated to use the
+default CMA size provided by upstream.
+
+Signed-off-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>
